TRACK STRUCTURE.

S?ECIFIGATION forming part of Letters Patent No. 555,772, dated March 3, 1896.

Application filed November 3, 1894. fierial No. 527,800. (No model.)

To all whmn it may concern:

ie it known that we, FRANK P. HOWE and VICTOR ANGERER, citizens of the United States, and residents of Philadelphia, Pennsylvania, have invented certain Improvements in Track Structures, of which the following is a specification.

Our invention relates to certain improvements in rail structures, for which application has been filed of even date herewith in the name of Edward Samuel, the present invention relating to improvements in adjusting and securing the special shape or crossing plate to the rail structure.

Referring to the accompanying drawings, Figure 1 is a plan view of a railway-frog made in accordance with our invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view of the same on the line 3 3, Fig. 1. Fig. 4 is a transverse section of the line 4: 4, Fig. 1. Fig. 5 is a perspective view of the special shape, and Fig. 6 is a view of a switchanate made in accordance with our invention.

Referring in the first instance to Figs. 1 to 5, inclusive, A and B are the rails, secured togetherbyacastmetal section D. The rails have perforated webs in the present instance,

. and in forming the structure the rails are mounted in suitable molds in which the fluid metal is so poured that it will flow through the perforations and along the sides of each rail. Thus, when the metal is cool, the several sections are firmly attached to the castingin their respective positions. The upper face of the cast-metal section is recessed between the rail-sections to receive the special shape E. The upper face of this shape or plate forms a continuation of the rails of the structure, as clearly shown in the drawings. We preferably make this special shape or plate E of metal of greater durability than the rails, and we shape the cavity in the cast metal section to accommodate the plate, as

shown in Figs. 3 and 4, and the edges d of the cavity are undercut, and the edges 6 of the plate are beveled on a similar line. The plate is somewhat smaller than the cavity, so that when it is adjusted in position liquid material f -such, for instance, as molten Babbitt metal, or any fluid substance which willset and hardenmay be poured into the space between the plate and the structure D, rigidly confining the plate to the structure.

We preferably form wedgeways d and e in the structure and in the plate d, and adapt ed to these ways are wedges e. The object of this construction is to enable a manufacturer to set the plate accurately in line with the rails of the structure and to assist the Babbitt or other metal that has been poured about the plate to rigidly confine it to its place. After the wedges are driven and the plate once set the liquid material can be poured into the spaces between the plate and the structure. The liquid material when set forms a positive lock for the wedges and prevents their displacement; but if it is wished to remove the plate at any time the metal or substance in the undercut part back of the wedges and elsewhere can be chipped or cut out, the wedges be driven back and the plate be lifted off. A new plate can then be put in its place. Thus it will be seen that by our improvement we are enabled to make a special shape of crossing-plate that can be readily removed, yet when in position is practically integral with the structure.

In Fig. 6 we have shown a switch-mate in which our invention is embodied, and it will be understood that any rail track structure can be made in accordance with our invention.

To claim as our invention 1. The combination of a frog or other rail structure having a recess at the crossingpoint, a metal plate adapted to said recess having an upper face which forms a continuation of the structure, with a wedge between the metal plate and the side walls of the structure, and cast metal or equivalent material between the plate and the structure whereby the plate and wedge are held in position, substantially as described.

2. The combination in a frog or other rail structure having a recess at the crossingpoint, with a metal plate adapted to said recess and having an upper face which forms a continuation of the structure, wedges for adjusting the plate laterally so as to align with ing the space between the inserted plate and the outer structure not occupied by the Wedges, substantially as described.

In testimony whereof We have signed our I 5 names to this specification in the presence of two subscribing Witnesses.
